Gingerman960/face-timelapse ? reverse-engineered prompt

Build me a desktop app for people who have lots of selfie photos over time and want to turn them into a smooth before and after timelapse.

I want to pick one reference photo and point it at a folder full of pictures, then have the app find my face in each one, keep just one photo per day, line up my eyes, nose, and mouth so every frame matches, and play the result back like a timelapse before exporting it as an MP4 or as a folder of aligned images. It should work completely offline on my machine, with no account or upload.

Please make the flow feel simple, with a scan screen, a review step for uncertain matches, a calendar style day picker, and a player with scrubber and export settings. I’d also like drag and drop for the reference photo or folder, session restore, progress and cancel for long jobs, and a light and dark theme. If you need to check anything, look up current docs online.
